To all whom t may concern.:

Be it known that l, Janine J. Heinlein)a of Philadelphia, in the State of Pennsyl Vania, have invented a certain new and useful improvement in Syringes, whereof the y following is a specification, reference being ,had to the accompanying drawings.'

My invention may be advantageously enibodied in asyringe for vaginal use, but or course may be otherwise utilized.v

As hereinafter described my invention. iii cludes' the combination with a tubular stein; of an exterior ovoid shell carried by said `stem and having a circumferential series of jet orifices extending through said shell; and an ovoid core in said shell, forming with said shell a series of separable chanl nels circumferentially spaced in said shell and leading to the respective jet oriiices," the outer Walls of said channels being:r formed by said shell, and the inner Walls oi' said cha-nu nels' being formed by said core; whereby Water passing throughsaid stem is equally distributed throughout the circumference of said' shell.

Myinveiition includes the 4various novel features of construction and arrangement hereinafter. more definitely speciied.

ln the drawin s':--l1`igure .lis a front end View of a nozz e conveniently embodying my improvement. Fig. ll is a longitudinal seetional'view taken on the line il, Il in Fig. l. Fig. lll is a transverse `sectional V view taken on the line lll, lili in Fig. ll'. Fig. lV is an inner end -viciv ot the conical shell with the removable core. Fig. V is a transverse sectional View similar to Fig'. HI but showing aniodified form of the invention.

Referring tofllig Il, the tubular stem 1 is provided atvits inlet end with means to detachably engage a Flexible tube 2 conveniently' With the beads tl and d. The opposite outlet end o' said stein l is provided with the annular flange 6 provided with the screw thread 7 fitting the screw thread 8 in the 4ovoid shell 9. iis shown in Fig, lll, said shell 9 has ridges ll extending longitudinally on its external surface, inner channels l2 coinciding with said ridgeamnd jet orices it arranged iii-series longitudinally in said shell 9, opening from said channels l2 through said ridges ll at one side thereof. rlhe arrangement described is such that Water may be `discl'iaijgcd .through said jet orifices `with a motion tangential to the pe- Specification of Letters ateiit.

rimeter ci' said shell. The liquid supplied through said stein l is. distributed equally to said channels l2 and ythence through said jet orifices lll hy the core member l5 which is conveniently formed as a hollow ovoid body having its inner end 16 tting in the flaring seat i8 in the proximal end of said steni l and provided with a series of radial channels 20 leadiine from said stein to the channels l2 in said shell 9.

Although l prefer to provide the nozzle Yshell 9 with internal channels corresponding with the external'ridges thereof, I do not desire to limitinyself to such construc` tion. lior instance, a shell 22' such as is shown in Fig. l!" and otherwise like the shell 9 above described may have a smoothly circular internal surface and the Water be distributed to the respect-ive oriices 23 in the ridges 2li by Way of channels 25 in the core member 26 which otherwise may 'be like the core member l5 above described. More over, although, l have shown tliecore member 15 littingf in thc end of the tibularstem l. and provided with a series of radial chanuelsileading from said stein to evenly dis-'1 tribute' the Water therefrom, it is to be understood that said core may be otherwise shaped .ll-do not desire to limit myself. to the preoise details of construction and arrangementabove described as it is obvious that various inodiiications may loe made therein Without.

rigid tubular stem having means at one'end to engage a dexible tube and having' an annular vscrew threaded flange at the otl'ller end with an outwardly flared seat concentric with the passageway through said stem; of Vit hollow ovoid shell detachably connected with said llange, by an internal screw thread at the larger end of said shell7 having ridges" extending longitudinally on its external surface, and jet oriices,`arranged in series longitudinally in said shell, opening through the latter tangentially with respect to its axis, through said ridges at one side thereof; a hollow sealed ovoid core inclosed by said shell in separable relation therewith, having a series of radial channels in its larger end concentric With the axis of said stem and fitted in the outwardly flared seat of the latter; and, means forming separate channels between said core and shell respectively in registry with the radial channels in said core and local to the respective series of orifices in said shell; whereby, water passing through said stem is distributed by said core in separate streams to the respective series of orifices with said fiange, by an internal screwthread at the larger end of said shell, liaving ridges extending longitudinally on its external surface, and jet orifices, arranged in' series longitudinally in sai-d shell, opening through the latter tangentially with respect to its axis, through said ridges at one side thereof; a hollow sealed ovoid core inclosed by said'shell in separable relation therewith, having its larger end concentric with the axis of said stein and fitted in the outwardly flared seat of the latter; and7 means forming separate channels between said core and shell respectively in registry with the respective series of orifices in said shell; whereby, water passing through said stem is'distributed by said core iii separate streams to the respective series of orifices to equalize the distribution of water throughout` the circumference of said shell.V

3. In a syringe, the combination with a rigid tubular stem having means at one end to engage a flexible tube and having an annular flange at the other end with an outwardly flared seat concentric withv the passageway'through said stein; ofA a hollow ovoid shell detachably connected with said flange, at the larger end of said shelhhaving ridges extending longitudinally on its external surface, and jet orifices, arranged in series longitudinally in said shell, open` lchannels in said core and local to the respective series of orifices in said shell;

whereby, water passingtlirough said Stein is distributed by said core in separate streams to the respective series of orices toequalize the distribution of water throughout the circumference of said shell.

4:. In a syringe, the combination 'with a tubular stem; of an exterior ovoid shell carried by said stem and having a circumieren- 'tial series of jet orifices extending through said shell; and an ovoid core in said shell.l forming with said shell a series of separable channels circumferentially spaced in said shell and leading to the respective jet orifices, the outer-walls of said channels being formed by sai-d shell, and the inner walls of said channels being foi-med by said core; whereby, water passing through said stein is equally distributed throughout the circumference of saidl shell.

.In testimony whereof I have hereunto signed my name at fPhiladelphia, Pennsylvania, this tenth day of November, 1909.
